Description

TECHNICAL FIELD

[0001] The application relates to the field of river regulation, in particular to a river regulation engineering environment-friendly dredging device. BACKGROUND

[0002] River regulation engineering is a basic facility in river regulation and maintenance, which completes dredging treatment of the river channel by means of a dredging device. The dredging device is commonly used in the field of water conservancy and environmental protection.

[0003] In the related art, a river regulation engineering environment-friendly dredging device is disclosed in Chinese Patent No. CN114875992A, which comprises a dredging vehicle body, a pushing mechanism, a dredging mechanism, a pretreatment structure fixedly installed on the dredging mechanism, and a dredging machine. The dredging mechanism comprises a fixing frame, a mud shield, a mud guide pipe fixedly connected to the mud shield, and a mud conveying pipe fixedly connected to the mud guide pipe. The pretreatment structure is arranged in the flow guide cover and breaks the sludge.

[0004] When working, the dredging vehicle body moves, so that the pushing mechanism accumulates the sludge in front of the moving direction of the dredging vehicle body, and then the dredging machine is started to suck the sludge on the pushing mechanism into the flow guide cover. The pretreatment structure breaks the sludge in the flow guide cover, so that the sludge is not easy to block the dredging channel. After the sludge on the pushing mechanism is sucked out, there is a dredging space on the pushing mechanism, so that the dredging continues.

[0005] When the sludge in the river channel is accumulated in a large area, the pushing mechanism is difficult to push the sludge due to the large resistance when pushing the sludge, so that the moving speed of the dredging vehicle body is low, that is, the sludge pushed in unit time is less, resulting in low dredging efficiency. Therefore, it needs to be improved. SUMMARY

[0006] In order to improve the problem of low dredging efficiency, the application provides a river regulation engineering environment-friendly dredging device.

[0007] The river regulation engineering environment-friendly dredging device provided by the application adopts the following technical scheme:

[0008] A river regulation engineering environment-friendly dredging device for cleaning sludge in a river channel, comprising:

[0009] A moving vehicle body is arranged in the river channel, and a roller is rotatably connected to the bottom of the moving vehicle body, and the roller is in contact with the bottom wall of the river channel.

[0010] A dredging mechanism is arranged on the moving vehicle body and used for pushing the sludge in front of the moving direction of the moving vehicle body.

[0011] A suction mechanism is arranged on the moving vehicle body and above the dredging mechanism, and is used to suck the sludge on the dredging mechanism;

[0012] A cutting mechanism is arranged on the moving vehicle body, and includes a cutting knife and a driving assembly. The cutting knife is arranged on the side of the dredging mechanism away from the moving vehicle body, and is connected with the driving assembly. The driving assembly is connected with the moving vehicle body, and drives the cutting knife to swing up and down, so as to separate the sludge in front of the dredging mechanism in the moving direction of the dredging mechanism.

[0013] By using the above technical scheme, when in use, the moving vehicle body is placed in the river channel, and the moving vehicle body is driven to move towards the cutting knife. The roller rotates, and the driving assembly drives the cutting knife to swing up and down during the movement of the moving vehicle body, so as to cut the sludge accumulated in a large area on the river channel in front, so that the sludge is divided into several parts. Then, the dredging mechanism is moved to the sludge where the cutting mechanism has passed, and is in abutment with the sludge, so that the dredging mechanism is subjected to smaller resistance, and it is convenient to push the sludge to the dredging mechanism. Compared with directly pushing the accumulated sludge by the dredging mechanism, the operation is more convenient, so that the moving vehicle body drives the dredging mechanism to move more smoothly, that is, in a unit of time, the dredging mechanism pushes more sludge, so that the work efficiency is higher.

[0014] When a large amount of sludge is accumulated on the dredging mechanism, the suction mechanism is started, and the suction mechanism sucks away the sludge on the dredging mechanism, so that the space on the dredging mechanism for accumulating sludge is empty, so that when the moving vehicle body continues to move, the dredging mechanism can still accumulate sludge, and the dredging process can continue.

[0015] Optionally, the driving assembly includes:

[0016] A rotating disc, the moving vehicle body is fixed with a connecting rod, the center of the rotating disc is rotatably connected to the connecting rod, and the rotating disc is vertically placed;

[0017] A driving rod, the top end of the driving rod is hingedly connected to the side wall of the rotating disc;

[0018] A fixed rod, the fixed rod is fixed to the moving vehicle body through the mounting rod;

[0019] A transmission rod, one end of the transmission rod is hingedly connected to the fixed rod, and the other end of the transmission rod is fixed with the cutting knife. The bottom end of the driving rod is located at the cutting knife, and is hingedly connected to the transmission rod.

[0020] By adopting the above technical scheme, when the mobile vehicle body moves, the rotating disc is driven to rotate, so that one end of the driving rod moves around the center of the rotating disc, thereby moving the bottom end of the driving rod up and down, and the driving rod is connected with the transmission rod, and the distance between the driving rod and the fixed rod is unchanged due to the unchanged length of the transmission rod, so that the bottom end of the driving rod rotates on the transmission rod to adapt the distance between the bottom end of the driving rod and the fixed rod, that is, the transmission rod swings up and down around the connection position of the transmission rod and the fixed rod, thereby making the cutting knife make circular arc motion around the connection position of the transmission rod and the fixed rod with the transmission rod as the radius, so that the cutting knife moves up and down while swinging left and right, realizing cutting and scattering of the sludge, so that the cutting of the sludge is more thorough.

[0021] Optionally, the rotating disc is connected with one of the rollers through a transmission belt, the transmission belt comprises a driving wheel, a driven wheel and a belt, the driving wheel is coaxially fixed with the roller, the driven wheel is coaxially fixed with the rotating disc, and the belt is sleeved on the driving wheel and the driven wheel, and the driving wheel rotates to drive the belt to move and drive the driven wheel to rotate.

[0022] By adopting the above technical scheme, when the mobile vehicle body moves, the roller rotates to drive the driving wheel to rotate, so that the belt drives the driven wheel to rotate, thereby driving the rotating disc to rotate, so that the driving rod moves to realize the up-and-down swinging of the cutting knife to cut the sludge, and when the mobile vehicle body stops, the cutting knife also stops due to the loss of power, that is, the mobile vehicle body moves to cut the sludge on the river channel in front, and the cutting is synchronous and has high accuracy.

[0023] Optionally, the dredging mechanism comprises:

[0024] The dredging plate is horizontally arranged and located between the mobile vehicle body and the cutting knife, the side wall of the dredging plate abuts against the side of the mobile vehicle body close to the cutting knife, and the dredging plate can contact the bottom wall of the river channel.

[0025] The electric push rod is arranged on the mobile vehicle body, the output end of the electric push rod is fixed with a moving rod, the moving rod is fixedly connected with the side wall of the dredging plate, and the electric push rod is used to drive the moving rod to move the dredging plate up and down.

[0026] By adopting the technical scheme, in the initial state, the bottom wall of the dredging plate is in contact with the bottom wall of the river channel, when the mobile vehicle body moves, the dredging plate slides on the river channel, thereby pushing the silt on the river channel, so that the silt is accumulated on the dredging plate. When more silt is accumulated on the dredging plate, the suction mechanism is started to extract the silt on the dredging plate, at the same time, the electric push rod is started to drive the moving rod to move upward, thereby driving the dredging plate to move upward, so that the dredging plate continuously approaches the suction mechanism, thereby facilitating the suction mechanism to extract the silt on the dredging plate, and in the process of upward movement of the dredging plate, the dredging plate also slides on the side wall of the mobile vehicle body, thereby scraping the silt on the side wall of the mobile vehicle body close to the cutting knife to the dredging plate and being extracted by the suction mechanism, thereby realizing the cleaning of the side wall of the mobile vehicle body.

[0027] Optionally, an air suction port is provided on the side of the mobile vehicle body close to the cutting knife, a filter plate is fixed at the opening of the air suction port, the filter plate is used to block the air suction port to limit the large silt from entering the mobile vehicle body through the air suction port, the filter plate extends downward to be in contact with the bottom wall of the river channel, the side wall of the dredging plate is in abutment with the side wall of the filter plate close to the cutting knife, and an air extraction port is provided on the top wall of the mobile vehicle body, the suction mechanism is in communication with the air extraction port and is used to extract the gas in the mobile vehicle body to the suction mechanism.

[0028] By adopting the technical scheme, when the mobile vehicle body moves, the dredging plate pushes the silt on the river channel on the forward path, the suction mechanism is started to extract the gas in the mobile vehicle body, so that the negative pressure is generated in the mobile vehicle body, thereby enabling the gas outside the mobile vehicle body to enter the mobile vehicle body from the air suction port, and then the silt is sucked to adhere to the filter plate, the filter plate plays a filtering role, so that the large silt cannot pass through the pores on the filter plate to enter the mobile vehicle body, but is left between the dredging plate and the filter plate, thereby reducing the possibility that the dredging plate pushes the silt to move forward of the moving direction of the dredging plate or diffuses to the two sides of the dredging plate, so that the pushed silt can be accumulated on the dredging plate, thereby facilitating the cleaning of the silt in the river channel.

[0029] After the silt is sucked and adhered to the filter plate by the gas, the gas still applies a moving suction force to the silt to the inside of the mobile vehicle body, thereby realizing the dehydration of the silt, reducing the volume of the silt, enabling more silt to be accumulated on the dredging plate, and reducing the weight of the silt on the dredging plate, so that the gravity of the dredging plate extruded downward on the river channel is smaller, thereby enabling the dredging plate to slide more smoothly on the river channel.

[0030] Optionally, the suction mechanism comprises:

[0031] A suction pipe is arranged on the top of the mobile vehicle body, one end of the suction pipe is open toward the dredging plate, a connecting hole is provided on the side wall of the suction pipe, and the connecting hole is in communication with the air extraction port.

[0032] The suction machine is arranged on the moving vehicle body and is communicated with the other end of the suction pipe to extract the gas in the suction pipe.

[0033] By adopting the above technical scheme, the suction machine is started to generate negative pressure in the suction pipe, so that the gas is sucked into the suction pipe from the suction pipe towards one end of the dredging plate, the sludge on the lower dredging plate is sucked into the suction pipe, at the same time, the gas in the moving vehicle body enters the suction pipe through the air suction port and the connecting hole to generate negative pressure in the moving vehicle body, and then the gas outside the moving vehicle body is sucked into the moving vehicle body through the air suction port.

[0034] Optionally, the suction pipe is provided with a blocking assembly for blocking the suction pipe or the connecting hole, and the blocking assembly comprises:

[0035] The rotating rod is arranged in the suction pipe, and the end of the rotating rod is rotationally connected to the suction pipe;

[0036] The blocking plate is located in the suction pipe, one side of the blocking plate is fixedly connected with the rotating rod, the blocking plate can block the connecting hole when the blocking plate is turned to be horizontal, and the blocking plate blocks the communication between the two ends of the suction pipe when the blocking plate is turned to be vertical.

[0037] By adopting the above technical scheme, when the moving vehicle body moves and the dredging plate scrapes the sludge on the river channel, the blocking plate is in a vertical state, that is, the circumferential side wall of the blocking plate is attached to the inner wall of the suction pipe to cut off the suction pipe, so that the end of the suction pipe towards the dredging plate has no suction, and at this time, the air suction port is communicated with the suction pipe through the connecting hole, so that the moving vehicle body generates negative pressure, that is, the air suction port has suction, which facilitates the accumulation of sludge on the dredging plate. When the dredging plate accumulates too much sludge, the rotating rod is driven to rotate, so that the blocking plate is turned from the vertical state to the horizontal state towards the suction machine, that is, the blocking plate blocks the connecting hole, so that the moving vehicle body is not communicated with the suction pipe, that is, the moving vehicle body has no negative pressure, and the air suction port has no suction, and at this time, the two ends of the suction pipe are communicated, that is, the end of the suction pipe towards the dredging plate generates suction, so that the sludge on the lower dredging plate is sucked into the suction pipe, and the sludge on the dredging plate is not tightly attached to the filter plate due to the fact that the air suction port has no suction, so as not to hinder the sludge on the dredging plate moving upwards into the suction pipe.

[0038] Optionally, the moving vehicle body is provided with a rotating assembly for driving the rotating rod to rotate, and the rotating assembly comprises:

[0039] The rotating gear, one end of the rotating rod extends out of the suction pipe and is coaxially fixed with the rotating gear;

[0040] The rotating rack is vertically arranged and is slidingly connected to the side wall of the moving vehicle body in the vertical direction, the rotating rack is engaged with the rotating gear, the side wall of the rotating rack is fixed with an abutting block, and the moving rod can abut against the top wall of the abutting block;

[0041] The advancing spring is fixed at one end to the moving vehicle body and at the other end to the rotating rack, and is used for advancing the rotating rack upward.

[0042] By adopting the above technical scheme, in the initial state, the dredging plate is located at the bottom and abuts against the bottom wall of the river channel, at this time, the moving rod abuts against the abutting block and exerts a downward pressure on the abutting block, so that the advancing spring is compressed, and the blocking plate is in a vertical state. When the silt on the dredging plate is too much and needs to be cleaned, the electric push rod is started, so that the moving rod drives the dredging plate to move upward, so that the abutting block loses the extrusion force, the advancing spring restores the deformation, and the rotating rack is advanced upward, thereby driving the rotating gear to rotate, that is, the rotating rod drives the blocking plate to rotate to a horizontal state, and the connecting hole is blocked, so that the suction port loses the suction force of adsorbing the silt on the filter plate, and the suction pipe end generates the suction force of sucking the silt on the dredging plate, thereby realizing the cleaning of the silt on the dredging plate.

[0043] Optionally, the moving vehicle body is provided with a baffle, the baffle is located between the suction port and the filter plate, and is used for limiting small pieces of silt entering the moving vehicle body to reach the suction port through the baffle, the bottom of the baffle is fixed with a sealing plate through a positioning rod, the sealing plate is perpendicular to the baffle, the positioning rod is rotatably connected to the moving vehicle body, the bottom of the moving vehicle body is provided with a discharge port, the sealing plate can block the discharge port, and the moving vehicle body is provided with a limiting assembly for limiting the sealing plate from blocking the discharge port.

[0044] By adopting the above technical scheme, in the initial state, the sealing plate is horizontally arranged and blocks the discharge port, the limiting assembly increases the stability of the sealing plate in maintaining this state, and the baffle is vertically arranged. When the suction port is suctioned, the suction port generates a suction force to adsorb the silt on the filter plate, the filter plate limits the passage of large pieces of silt, and small pieces of silt can pass through the pores on the filter plate and enter the moving vehicle body. When the small pieces of silt move to the baffle, the pores on the baffle limit the passage of small pieces of silt, so that the silt is not easy to reach the suction port to block the suction port, and the suction of the suction port is not easy to be affected.

[0045] When the sludge is adsorbed on the filter plate, the suction in the moving vehicle body can dehydrate the sludge, and the water can be deposited in the moving vehicle body through the filter plate and the baffle. When there is too much water in the moving vehicle body, first move the limiting assembly so that the limiting assembly is separated from the sealing plate, then rotate the positioning rod so that the sealing plate moves downward, thereby separating the sealing plate from the inner wall of the discharge port, that is, the discharge port is in an open state. The sealing plate is in an inclined downward state at this time, which also plays a guiding role, facilitating the sludge and water in the moving vehicle body to be discharged from the discharge port. At the same time, the top wall of the baffle is separated from the inner wall of the moving vehicle body, so that there is a gap between the baffle and the inner wall of the moving vehicle body. At this time, the moving vehicle body is flushed to wash the sludge on the baffle down and move it from the gap between the baffle and the inner wall of the moving vehicle body to the discharge port.

[0046] Optionally, the limiting assembly comprises:

[0047] A limiting rod is vertically arranged and rotationally connected to the moving vehicle body;

[0048] Two limiting semicircular plates are horizontally arranged, and the straight edges of the two limiting semicircular plates are fixedly connected to the limiting rod. The two limiting semicircular plates are arranged in an up-down manner, and the sealing plate can be inserted between the two limiting semicircular plates.

[0049] By adopting the above technical scheme, when the sealing plate is in a horizontal state and blocks the discharge port, the limiting rod is rotated so that the two limiting semicircular plates are moved into the moving vehicle body. At this time, the sealing plate is relatively inserted between the two limiting semicircular plates, and the two limiting semicircular plates prevent the sealing plate from moving upward or downward, that is, the sealing plate cannot rotate about the positioning rod. The stability of the sealing plate blocking the discharge port is increased. The sludge and water in the moving vehicle body are received on the sealing plate, so that the sealing plate exerts a larger pressure on the limiting semicircular plate at the bottom, which in turn resists the limiting semicircular plate, so that the limiting semicircular plate is not easy to rotate, that is, the sealing plate and the limiting semicircular plate restrict each other.

[0050] In summary, the present application has at least one of the following beneficial effects:

[0051] 1. In use, the moving vehicle body is placed in the river channel, and the moving vehicle body is driven to move towards the direction of the cutting knife. The roller rotates, and the driving assembly drives the cutting knife to swing up and down during the movement of the moving vehicle body, thereby cutting the large-area accumulated sludge on the front river section, so that the accumulated sludge is divided into several parts. Then, the dredging mechanism moves to the sludge where the cutting mechanism has passed and abuts against the sludge, so that the dredging mechanism is subjected to smaller resistance, facilitating the pushing of the sludge onto the dredging mechanism. Compared with directly pushing the accumulated sludge through the dredging mechanism, the operation is more convenient, so that the moving vehicle body drives the dredging mechanism to move more smoothly, that is, in a unit of time, the dredging mechanism pushes more sludge, so that the work efficiency is higher.

[0052] 2. When the mobile vehicle moves, the drive disc rotates, causing one end of the drive rod to move about the center of the disc. This causes the bottom of the drive rod to move up and down, which in turn causes the transmission rod to swing up and down about the connection between the transmission rod and the fixed rod. This causes the cutting blade to move in an arc about the connection between the transmission rod and the fixed rod, with the transmission rod as the radius. As the cutting blade moves up and down, it also swings left and right, thus cutting and dispersing the silt, making the cutting of the silt more thorough. Attached Figure Description

[0056] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0057] This application discloses an environmentally friendly dredging device for river regulation projects. (Refer to...) Figure 1 The environmental dredging device for river regulation projects includes a mobile vehicle 10, which is a square box. Rollers 11 are rotatably connected to the bottom of the mobile vehicle 10. A dredging mechanism 20 is provided on the mobile vehicle 10. The dredging mechanism 20 is located in front of the mobile vehicle 10 in the direction of movement, that is, at the front of the mobile vehicle 10. The dredging mechanism 20 is in contact with the bottom wall of the river. When the mobile vehicle 10 moves, the dredging mechanism 20 is used to push and scoop up the silt in front of the mobile vehicle 10.

[0058] Reference Figure 1The suction mechanism 30 is arranged on the moving vehicle body 10 and is located directly above the dredging mechanism 20, and is used for sucking the silt on the dredging mechanism 20, so as to clean the silt on the dredging mechanism 20, make the space for stacking the silt on the dredging mechanism 20 empty, and make the dredging mechanism 20 continue to stack the silt when the moving vehicle body 10 continues to move, so as to continuously carry out the dredging process and improve the work efficiency.

[0059] With reference to Figure 1 When the silt in the river channel is stacked in a large area, the dredging mechanism 20 is difficult to push the silt, and the movement of the moving vehicle body 10 is limited. In order to prevent the dredging efficiency from being reduced, the cutting mechanism 40 for cutting the silt in front is arranged on the moving vehicle body 10. The cutting mechanism 40 comprises a driving assembly 42 and a cutting knife 41. The cutting knife 41 is located on the side of the dredging mechanism 20 away from the moving vehicle body 10, and the cutting edge of the cutting knife 41 can be in contact with the bottom wall of the river channel. The cutting knife 41 is connected with the driving assembly 42, and the driving assembly 42 is connected with the moving vehicle body 10.

[0060] With reference to Figure 1 The driving assembly 42 comprises a rotating disc 421, a driving rod 422, a fixed rod 423 and a transmission rod 424. The connecting rod 4211 is fixed on the moving vehicle body 10 and is located at the top of the moving rod 211 and is horizontally arranged. The rotating disc 421 is vertically placed, and the center of the rotating disc 421 is rotatably connected to the connecting rod 4211 through a rotating shaft. The rotating shaft is connected to one of the rollers 11 through the transmission belt 50. The transmission belt 50 comprises a driving wheel 51, a driven wheel 52 and a belt 53. The driving wheel 51 is coaxially fixed with one of the rollers 11. The driven wheel 52 is coaxially fixed with the rotating disc 421. The belt 53 is sleeved on the driving wheel 51 and the driven wheel 52. When the driving wheel 51 rotates, it drives the belt 53 to move and drives the driven wheel 52 to rotate.

[0061] With reference to Figure 1 The top end of the driving rod 422 is rotatably connected to the rotating disc 421, and the connection between the driving rod 422 and the rotating disc 421 is located at a position other than the center of the rotating disc 421. That is, when the rotating disc 421 rotates, one end of the driving rod 422 will rotate around the central axis of the rotating disc 421. The bottom end of the driving rod 422 is rotatably connected to the transmission rod 424. The end of the transmission rod 424 away from the moving vehicle body 10 is rotatably connected to the fixed rod 423. The fixed rod 423 is horizontally placed and is arranged perpendicular to the moving direction of the moving vehicle body 10. The mounting rod 4231 is fixed on the moving vehicle body 10 and is parallel to the connecting rod 4211. The mounting rod 4231 is fixedly connected to the connecting rod 4211. The cutting knife 41 is arranged along the length direction of the fixed rod 423. The cutting knife 41 is fixedly connected to the end of the transmission rod 424 close to the moving groove box body.

[0062] When the mobile vehicle body 10 moves, the rollers 11 rotate, the driving driving wheel 51 rotates, the belt 53 drives the driven wheel 52 to rotate, the rotating disc 421 rotates, one end of the driving rod 422 moves around the center of the rotating disc 421, the bottom end of the driving rod 422 moves up and down, the driving rod 422 is connected with the transmission rod 424, the length of the transmission rod 424 does not change, the distance between the driving rod 422 and the fixed rod 423 does not change, the bottom end of the driving rod 422 rotates on the transmission rod 424, the distance between the bottom end of the driving rod 422 and the fixed rod 423 is adapted, that is, the transmission rod 424 swings up and down around the connection between the transmission rod 424 and the fixed rod 423, and the cutting knife 41 swings left and right around the center of the connection between the transmission rod 424 and the fixed rod 423, and the cutting knife 41 moves up and down and swings left and right, so that the cutting of the silt is more complete.

[0063] Referring to Figure 1 When the mobile vehicle body 10 stops, the cutting knife 41 also stops due to lack of power, that is, the mobile vehicle body 10 moves, and the cutting knife 41 cuts the silt on the front river channel, which is synchronous and has high accuracy.

[0064] Referring to Figure 1 The dredging mechanism 20 comprises a dredging plate 21 and an electric push rod 22. The dredging plate 21 is horizontally arranged and located between the mobile vehicle body 10 and the cutting knife 41. The cutting knife 41 is arranged along the length direction of the fixed rod 423. The dredging plate 21 can contact the bottom wall of the river channel. The electric push rod 22 is fixed on the mobile vehicle body 10 by bolts. The output end of the electric push rod 22 faces downward and is fixed with a moving rod 211. The moving rod 211 is fixedly connected with the end wall in the length direction of the dredging plate 21. The electric push rod 22 is used to drive the moving rod 211 to move the dredging plate 21 up and down.

[0065] Referring to Figure 1 and Figure 1 An air inlet 12 is arranged on the side of the mobile vehicle body 10 close to the cutting knife 41. A filter plate 90 is arranged at the air inlet 12. The filter plate 90 is vertically arranged and fixedly connected with the side wall of the air inlet 12 of the mobile vehicle body 10. The filter plate 90 blocks the air inlet 12 to prevent large silt from entering the mobile vehicle body 10 through the air inlet 12. The bottom of the filter plate 90 extends downward to contact the bottom wall of the river channel. The side wall of the dredging plate 21 abuts against the side wall of the filter plate 90 close to the cutting knife 41.

[0066] In the initial state, the bottom wall of the dredging plate 21 is in contact with the bottom wall of the river channel. When the moving vehicle body 10 moves, the dredging plate 21 slides on the river channel, thereby pushing the silt on the river channel, so that the silt is accumulated on the dredging plate 21. When the dredging plate 21 accumulates a large amount of silt, the silt on the dredging plate 21 is extracted by starting the suction mechanism 30, and at the same time, the electric push rod 22 is started to drive the moving rod 211 to move upward, thereby driving the dredging plate 21 to move upward, so that the dredging plate 21 continuously approaches the suction mechanism 30, thereby facilitating the suction mechanism 30 to extract the silt on the dredging plate 21.

[0067] Referring to Figure 2 and Figure 1 At the same time, the dredging plate 21 also slides on the side wall of the filter plate 90 during the upward movement, thereby scraping the side wall of the filter plate 90 close to the cutting knife 41 onto the dredging plate 21 and being extracted by the suction mechanism 30, thereby achieving the cleaning of the side wall of the moving vehicle body 10.

[0068] Referring to Figure 2 and Figure 1 The suction mechanism 30 includes a suction pipe 31 and a suction machine. The suction pipe 31 is fixed to the top of the moving vehicle body 10, one end of the suction pipe 31 is open towards the dredging plate 21, and the other end is in communication with the suction machine. The suction machine is fixed to the top wall of the moving vehicle body 10 by bolts. A connection hole 311 is formed in the side wall of the suction pipe 31, and an air outlet 13 is formed through the top wall of the moving vehicle body 10. The connection hole 311 is in communication with the air outlet 13.

[0069] The suction machine 32 is started to generate negative pressure in the suction pipe 31, thereby sucking the gas from the one end of the suction pipe 31 into the suction pipe 31, achieving the suction of the silt on the lower dredging plate 21 into the suction pipe 31. At the same time, the gas in the moving vehicle body 10 enters the suction pipe 31 through the air outlet 13 and the connection hole 311, so that negative pressure is generated in the moving vehicle body 10, thereby causing the gas outside the moving vehicle body 10 to enter the moving vehicle body 10 through the air inlet 12, thereby sucking the silt against the filter plate 90. The filter plate 90 plays a filtering role, so that large pieces of silt cannot pass through the pores on the filter plate 90 and enter the moving vehicle body 10, but are left between the dredging plate 21 and the filter plate 90.

[0070] Referring to Figure 2 and Figure 1 During the movement of the dredging plate 21, the silt is pushed, and it is not easy to push the silt in front of the movement direction of the dredging plate 21 or to spread to the sides of the dredging plate 21, so that the pushed silt can be accumulated on the dredging plate 21, thereby facilitating the cleaning of the silt in the river channel.

[0071] When the sludge is sucked and adhered to the filter plate 90, the gas still applies a moving force to the sludge to move into the moving vehicle body 10, so as to realize the dehydration of the sludge, reduce the volume of the sludge, enable more sludge to be accumulated on the dredging plate 21, and reduce the weight of the sludge on the dredging plate 21, so that the gravity of the dredging plate 21 extruded downward on the river is smaller, thereby making the sliding of the dredging plate 21 on the river more smooth.

[0072] With reference to Figure 2 and Figure 1 , in order to prevent the sludge adhered to the filter plate 90 by the suction at the suction port 12 when the suction pipe 31 sucks the sludge on the dredging plate 21, affecting the cleaning of the sludge on the dredging plate 21, a blocking assembly 60 is arranged in the suction pipe 31, the blocking assembly 60 comprises a rotating rod 61 and a blocking plate 62, the rotating rod 61 is arranged in the suction pipe 31, the end of the rotating rod 61 is rotatably connected to the suction pipe 31, the blocking plate 62 is arranged in the suction pipe 31, one side of the blocking plate 62 is fixedly connected with the rotating rod 61, when the blocking plate 62 is turned to be horizontal, the connecting hole 311 is blocked, when the blocking plate 62 is turned to be vertical, the two ends of the suction pipe 31 are communicated.

[0073] When the moving vehicle body 10 moves and the dredging plate 21 scrapes the sludge on the river, the blocking plate 62 is in a vertical state, that is, the circumferential side wall of the blocking plate 62 adheres to the inner wall of the suction pipe 31 to cut off the suction pipe 31, so that the end of the suction pipe 31 towards the dredging plate 21 has no suction, and at this time the suction port 13 communicates with the suction pipe 31 through the connecting hole 311, so that the negative pressure in the moving vehicle body 10 is generated, that is, the suction at the suction port 12 is generated, which facilitates the accumulation of the sludge on the dredging plate 21.

[0074] With reference to Figure 2 and Figure 1 When the sludge on the dredging plate 21 is accumulated too much, the rotating rod 61 is driven to rotate, so that the blocking plate 62 is turned from the vertical state to the horizontal state towards the direction of the sludge suction machine 32, that is, the blocking plate 62 blocks the connecting hole 311, so that the moving vehicle body 10 is not communicated with the suction pipe 31, that is, there is no negative pressure in the moving vehicle body 10, and there is no suction at the suction port 12, and at this time the two ends of the suction pipe 31 are communicated, that is, the suction at the end of the suction pipe 31 towards the dredging plate 21 is generated, so as to suck the sludge on the lower dredging plate 21 into the suction pipe 31, and the sludge on the dredging plate 21 is not adhered to the filter plate 90 due to the absence of suction at the suction port 12, so as not to hinder the sludge on the dredging plate 21 moving upward into the suction pipe 31.

[0075] With reference to Figure 2 and Figure 1A rotating assembly 70 is arranged on the mobile vehicle body 10 for driving the rotating rod 61 to rotate, the rotating assembly 70 comprises a rotating gear 71, a rotating rack 72 and a propelling spring 73, one end of the rotating rod 61 extends out of the suction pipe 31 and is coaxially fixed with the rotating gear 71, the rotating rack 72 is vertically arranged, and the side wall of the rotating rack 72 is embedded on the side wall of the mobile vehicle body 10 and can move on the mobile vehicle body 10 in the vertical direction, the rotating rack 72 is engaged with the rotating gear 71, and the side wall of the rotating rack 72 is fixed with an abutting block 721, and the moving rod 211 can abut against the top wall of the abutting block 721. The propelling spring 73 is located at the bottom of the rotating rack 72, one end of the propelling spring 73 is fixed with the mobile vehicle body 10 through a mounting block, and the other end is fixed with the rotating rack 72.

[0076] In the initial state, the dredging plate 21 is located at the bottom, that is, abuts against the bottom wall of the river channel, at this time, the moving rod 211 abuts against the abutting block 721 and applies a downward pressure to the abutting block 721, so that the propelling spring 73 is compressed, and at this time, the blocking plate 62 is in a vertical state. When the silt on the dredging plate 21 needs to be cleaned due to excessive silt, the electric push rod 22 is started, so that the moving rod 211 drives the dredging plate 21 to move upwards, so that the abutting block 721 loses the extrusion force, the propelling spring 73 restores the deformation, and the rotating rack 72 is pushed upwards, thereby driving the rotating gear 71 to rotate, that is, the rotating rod 61 drives the blocking plate 62 to rotate to a horizontal state, and the connecting hole 311 is blocked, so that the suction port 12 loses the suction force for adsorbing the silt on the filter plate 90, and the suction pipe 31 end generates a suction force for sucking the silt on the dredging plate 21, thereby realizing the cleaning of the silt on the dredging plate 21.

[0077] Referring to Figure 2 and Figure 1 When the suction pipe 31 sucks the air of the mobile vehicle body 10, the filter plate 90 limits the large silt to pass through, but the small silt still enters the mobile vehicle body 10. In order to prevent the silt from blocking the suction port 13, the baffle 110 is arranged in the mobile vehicle body 10, the diameter of the aperture of the baffle 110 is smaller than that of the aperture of the filter plate 90, the baffle 110 is located between the suction port 13 and the filter plate 90, and the circumferential side wall of the baffle 110 is attached to the inner wall of the mobile vehicle body 10. When the small silt passes through the filter plate 90 and enters the mobile vehicle body 10, the small silt reaches the baffle 110, and the baffle 110 blocks the small silt from passing through, so that the silt cannot reach the suction port 13 to block the suction port 13.

[0078] When the mobile vehicle body 10 is pumping, the silt on the dredging plate 21 is dehydrated, and the water is stored in the mobile vehicle body 10. In order to enable the water in the mobile vehicle body 10 to be discharged, a discharge port 14 is provided through the bottom of the mobile vehicle body 10. A sealing plate 120 is fitted and arranged in the discharge port 14. The sealing plate 120 can completely block the discharge port 14. The sealing plate 120 is horizontally placed, that is, perpendicular to the baffle plate 110. The side of the sealing plate 120 close to the cutting knife 41 is fixedly connected with the bottom of the baffle plate 110 through a positioning rod 130 which is rotationally connected on the mobile vehicle body 10. When the sealing plate 120 blocks the discharge port 14 in a horizontal state, the mobile vehicle body 10 is provided with a limiting assembly 80 so that the sealing plate 120 maintains this state, thereby preventing the sealing plate 120 from being easily turned down by the weight of the water in the mobile vehicle body 10.

[0079] With reference to Figure 2 and Figure 1 , in the initial state, the sealing plate 120 is horizontally arranged and blocks the discharge port 14. The limiting assembly 80 increases the stability of the sealing plate 120 in maintaining this state, and the baffle plate 110 is vertically arranged. When the suction port 13 is pumping, suction is generated at the suction port 12, the silt is adsorbed on the filter plate 90, the filter plate 90 limits the passage of large pieces of silt, and small pieces of silt can pass through the pores on the filter plate 90 and enter the mobile vehicle body 10. When the small pieces of silt move to the baffle plate 110, the pores on the baffle plate 110 limit the passage of small pieces of silt, thereby preventing the silt from reaching the suction port 13 and blocking the suction port 13, so that the suction of the suction port 13 is not easily affected.

[0080] When the silt is adsorbed on the filter plate 90, the suction in the mobile vehicle body 10 can dehydrate the silt, and the water can be deposited in the mobile vehicle body 10 through the filter plate 90 and the baffle plate 110. When there is too much water in the mobile vehicle body 10, the limiting assembly 80 is first moved to separate the limiting assembly 80 from the sealing plate 120, and then the positioning rod 130 is rotated to move the sealing plate 120 downward, so that the sealing plate 120 is separated from the inner wall of the discharge port 14, that is, the discharge port 14 is in an open state. The sealing plate 120 is in an inclined downward state at this time, which also plays a guiding role, facilitating the discharge of the silt and water in the mobile vehicle body 10 from the discharge port 14. At the same time, the top wall of the baffle plate 110 is also separated from the inner wall of the mobile vehicle body 10, so that there is a gap between the baffle plate 110 and the inner wall of the mobile vehicle body 10. At this time, the silt on the baffle plate 110 is washed down and moved to the discharge port 14 from the gap between the baffle plate 110 and the inner wall of the mobile vehicle body 10.

[0081] With reference to Figure 2 and Figure 1 Figure 2The limiting assembly 80 comprises a limiting rod 81 and two limiting half-discs 82. The limiting rod 81 is vertically arranged and penetrates the moving vehicle body 10. The bottom end of the limiting rod 81 is rotationally connected to the moving vehicle body 10, and the top end extends out of the top wall of the moving vehicle body 10. The two limiting half-discs 82 are horizontally arranged. The straight edges of the two limiting half-discs 82 are fixedly connected to the limiting rod 81. The two limiting half-discs 82 are arranged in an up-down manner. The sealing plate 120 can be inserted between the two limiting half-discs 82.

[0082] When the sealing plate 120 blocks the discharge port 14 in the horizontal state, the limiting rod 81 is rotated, so that the two limiting half-discs 82 are turned into the moving vehicle body 10. At this time, the sealing plate 120 is relatively inserted between the two limiting half-discs 82. The two limiting half-discs 82 make the sealing plate 120 unable to move upward or downward, that is, the sealing plate 120 cannot rotate around the positioning rod 130. The stability of the sealing plate 120 blocking the discharge port 14 is increased. The sealing plate 120 above receives the sludge and water in the moving vehicle body 10, so that the sealing plate 120 exerts a larger pressure on the limiting half-discs 82 at the bottom, which in turn resists the limiting half-discs 82, so that the limiting half-discs 82 are not easy to rotate. That is, the sealing plate 120 and the limiting half-discs 82 restrict each other.

[0083] The implementation principle of the river regulation engineering environment-friendly dredging device is as follows: in use, the moving vehicle body 10 is placed in the river, and the moving vehicle body 10 is driven to move towards the direction of the cutting knife 41. The roller 11 rotates, and the driving assembly 42 drives the cutting knife 41 to swing up and down during the movement of the moving vehicle body 10, so as to cut the sludge accumulated on the front river section, so that the sludge is divided into several parts. Then, the dredging mechanism 20 moves to the sludge where the cutting mechanism 40 has passed and abuts against the sludge, so that the resistance received by the dredging mechanism 20 is smaller, which facilitates the pushing of the sludge to the dredging mechanism 20. Compared with directly pushing the accumulated sludge by the dredging mechanism 20, the operation is more convenient, so that the moving vehicle body 10 drives the dredging mechanism 20 to move more smoothly, that is, in a unit time, the dredging mechanism 20 pushes more sludge, so that the work efficiency is higher.

[0084] When a large amount of sludge is accumulated on the dredging mechanism 20, the pumping mechanism 30 is started to pump away the sludge on the dredging mechanism 20, so that the space for accumulating sludge on the dredging mechanism 20 is empty, so that when the moving vehicle body 10 continues to move, the dredging mechanism 20 can still accumulate sludge, so that the dredging process continues.

[0085] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
